SOLAR SYSTEM

Detailed explanation-1: -Comet tails get longer and more impressive as the comet gets closer to our Sun. As the comet approaches our Sun, it gets hotter and material is released more rapidly, producing a larger tail. Scientists estimate that a comet loses between 0.1 and 1 percent of its mass each time it orbits our Sun.

Detailed explanation-2: -Like all orbiting bodies, comets follow Kepler’s Laws-the closer they are to the Sun, the faster they move.

Detailed explanation-3: -Solar wind pushes the vapor in a direction away from the Sun to form the comet’s tail. For this reason, comet tails generally point away from the Sun. Comet tails are often very long.

Detailed explanation-4: -When a comet is in our solar system, most of the gravity affecting the comet’s motion is due to the Sun. As a comet gets closer to the Sun it moves faster and faster, because the closer an object is to the Sun the stronger the Sun’s gravity acts on it.

Detailed explanation-5: -The tail of the comet is gas and dust boiled off by the heat if the sun. So no new tail material is emitted once it gets away from the sun.
